We manufacture Finned Tubes by a special process in which a continuous strip of fin material is wound spirally on the tube, making it strong to withstand high internal pressure. The usage of finned tubes gives heat uniformly and increases the heat output depending upon the height of fins per unit length employed. Finned pipe and tubes are used within shell and tube type heat exchangers to enhance the heat transfer between the inside of the heat exchanger tube or pipe, and the outside. Finned pipes and tubes are commercially available in various sizes and materials.

These can be manufactured in maximum length of 6 meters along with outside diameter of pipe ranging from 6 to 73mm and the fining can be controlled from 2 to 9 fins per inch. We can manufacture finned tubes in U Bend, Coil & Straight lengths. The Fin size ranges from 4mm to 30mm.

Finned Pipe / Tube Design Considerations:

To be able to transfer heat well, the Finned Tube or pipe material must have adequate thermal conductivity . Heat energy transfer is increased by the effective fin area on the tube or pipe. The heat exchanger tube material will thermally expand differently at various temperatures, therefore, thermal stresses will be present along the heat exchanger. Additionally, stress will be induced by any high pressures from the applicable fluids. The tube and fin material should be galvanically compatible with all heat exchanger components and fluids for extended service periods under all operating conditions (temperatures, pressures, pH , etc.) . These requirements require careful selection of material which is : strong, thermally-conductive, and corrosion-resistant . The fin effectiveness in transferring a given quantity of heat is defined by: Fin efficiency = (Actual Heat Transferred) / (Heat which would be transferred in entire fin area were at base temperature).
